Fusion 360 render environment not responding?

[sebastian.pearson]

I'm trying to render an image in F360. If I change the appearance of the object in the render environment, it stays blank white. The object changes it's appearance in the design tab, but not in the render tab (which is where I'm hoping to see the change). If I render the objects they remain the blank white they started off as.

Have I missed some simple setting here? It's been a while since I used the render environment, but I never remember this being an issue (and I've successfully rendered images before).

I managed to sort things out with a restart and playing around with the lighting.
